Synthesis and VOCs adsorption properties of Diatomite/FAU-type zeolite composites
Adsorption technology utilizing zeolites as adsorbents is a highly efficient and cost-effective method for controlling the emission of volatile organic compounds (VOCs). Herein, two hierarchical diatomite/FAU-type zeolite composites were synthesized by a seeding-assisted secondary hydrothermal growth method and high-temperature hydrothermal dealumination, respectively. The adsorption properties of the composites for VOCs, such as toluene, ethyl acetate, n-heptane, methanol and acetone, were systematically evaluated. The pseudo-second-order model provided a perfect fit to adsorption kinetics, while the Langmuir model agreed the best with the adsorption isotherms. Furthermore, Dt/USY has remarkable recycling stability even after five regeneration cycles, resulting in outstanding VOCs adsorption efficacy.
期刊介绍：
Chemical Physics Letters has an open access mirror journal, Chemical Physics Letters: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review.
Chemical Physics Letters publishes brief reports on molecules, interfaces, condensed phases, nanomaterials and nanostructures, polymers, biomolecular systems, and energy conversion and storage.
Criteria for publication are quality, urgency and impact. Further, experimental results reported in the journal have direct relevance for theory, and theoretical developments or non-routine computations relate directly to experiment. Manuscripts must satisfy these criteria and should not be minor extensions of previous work.
